Application filed January 8,

To all whom it may concern:

Be it known that I, EUGENE .RUsTEnHoLz, citizen of the United States of America, residing at \V est Hoboken, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Fabric-Cutting Machines, of which the following is a specification.

.111 the embroidery art, scalloping machines are employed to cut around the scalloped edges of an embroidered piece of fab ric, which machines consist of a fabric sup port, fabric feeding means anda frame carrying an endless flexible blade.

These machines, however, cannot 'beemployed to cut between two rows of embroid-l ered design so as to divide the fabric into}: strips or hands to be used as socalled inser-f, tions and as far as I am aware no machines for this purpose have as yet been designed.

The main object of my invention is to provide a device whereby a piece of fabric con-M taining a number of rows of embroidered designs can be easily and quickly cut up or di-; vided into separate bands or strips. l Another object of my invention is to provide a device which can be easily and re movably applied to theframe of the well:

known scalloping machine without necessi-t tating any change in the construction of the latter, except the removal of the movable blade. i

A further object of my invention is to con-' struct the device so as to render it adjustable for different widths of bands or strips to be cut.

Another important object of my inven tion is to so arrange the cutting mechanism that when the point of the blade which cuts the fabric becomes blunt, the blade can be displaced longitudinally to present a new sharp edge, so that the blade will be lasting and can be used for a considerable time be fore it need be replaced by a new blade.

With these and other objects in view my invention consists in the construction, arrangement and combination of parts, as will be hereinafter described and set forth in the appended claims. 7

In the drawing, which forms part of this specification, and in which similar reference characters denote corresponding parts, Figure l is a side elevation of my device shown as applied to the well known frame of a scalloping machine; Fig. 2 is an enlarged front view of the device; Fig. 3 is an Specification of Lettersi'Patent.

enlarged sectional side view thereof showing. 1 some details of construction and Fig. at is a .erally is composed of two sections which are the embroidered-part from coming into the In lieu of the movable bladeemployedwith these machines, I provide my new cutting. device, which is constructed to"'be readily suspended from the arm 4 of the frame of the scalloping machine.

My cutting mechanism substantiallycomprises a member or plate 10 which is provided with an oblong recess or opening 11 forming a socket and the upper and lower sides 11, 11 of which are beveled (Figs. 2 and 8). Pivotally secured to the member 10 are arms 12, 12 which at their freecnds are arched as at 12 to correspond with the shape of the arm a so as to embrace the latter. The two arms are capable of being clamped together and around the arm 4 by means of a suitable clamping mechanism such as a bolt 13 and thumb nut 14. Engaging the socket ll of the member 10, is the blade carrier 9, which consists of a bar divided longitudinally and centrally into two sections 9 and 9 between which the blade 16 is adapted to be clamped or otherwise se cured. The sections are undercut at 9 and 9 so that when assembled they will'form between themselves a rest for the lower edge of the blade 16 and be capable of being tightened to securely hold theblade in position. The blade 16 is a flexible steel band having a beveled or cutting. edge 16 and adapted to extend longitudinally between the upper parts of the two seetionsof the bar 9 and to project with its sharp edge outwardly therefrom' (Fig/41') Tliesec'tion -i) of the carrier is formed at its rear end with a projection 9 conforming in "s"hapewith the crosssection of the recess 11 and the end "stirface 'w' of "s'a'id sction'is bvel'ed soas to bear on the plate when theprojecti'on 9 envages the opening 11.

10 Owing-to the shape -"0f the open-ing l-l and 30f the -projection Q the-carrier 9 will-extend at an anglejt'oj the-'membe'r 10 whiclr is-sus- :pendcd vertically, so that it will project slant-in g ly into the-path m": the fabricya-nd :thns present to the latter 'asingle: point-of :t-he cutting edge 16., \V hen the cutting point becomes} bltint, the knife can be displaced longitudinally to present anew entt-i ng 1point an dso on. 7 i

This enables the'adj'ustment of ;the, blade transversely 'to the path 'ofthe fabric,'acco1'cl-ing to the distances between two a dj dining; rows of embroideries.

One ofthejchief advantages ofiered by'my invention-is that thc device'can be nsed as an auxiliary implement for the Well known 80 sca'lloping machines, its attachment requiring no change of the machine exceptthe'relfiOVfll'Qffthe mOYflblG cutting band. I i y y A further advantage is thatthe-moifable blade used forthe; scalloping machine 'w-lien *accidentally severed can be --utilized'-"f0r'my ideyiceyhy cutting the sa me into pieces to fit inthecarrier. I

While I lia 'e-'-' :lesci'ilie d and shown one emhodiment of my invention, it is under- "stood tli'a'tva'rious modifications may be made in theconstruction Without departing from thepri'nciple of my invention.

What lclai-m and desire to secure by Letters Patent is:
